Digital Color Meter shows images as blurred on Retina Macs!

This isn't the usual issue of Digital Color Meter not returning the correct or expected colour values or anything like that!

I do a lot of retro graphics (8-bit and 16-bit computers and game consoles) work and so visit a lot of retro computer/console game websites. I've also just moved from a 2015 MacBook Air to a 2015 MacBook Pro and have immediately noticed with all the game screen/graphics images displayed on these websites as well as the thousands of images I've taken from these websites over the years are now displaying as blurred in Digital Color Meter's window, but display correctly on the MacBook Air.

Both the MacBook Air and Pro are running the same macOS version and therefore the same Safari version and with the same preferences settings and the same Digital Color Meter version (set to 'Display native values') All display preferences are also the same. Both are set to sRGB IEC61966-2.1 for the Display profile and scaling is 'Off' i.e. 'Default for Display' is selected.

It's not a display or Intel GPU fault with my MacBook Pro as the same blurring shows in Digital Color Meter on the M1/M2 Macs at the Apple Store. This points then to a bug in the way Digital Color Meter is translating the Retina pixels to virtual pixels before the area is output to it's window (set to minimum Aperture size).

The MacBook Air displays everything correctly since it doesn't have a Retina display. My MacBook Pro and all the M1/M2 Macs at the Apple Store do.

What I'm seeing is for every 2 pixels horizontally Digital Color Meter is averaging the colour of the pixels so a vertical white (RGB 255, 255, 255) 1 pixel wide line on a black (RGB 0, 0, 0) background will now show as a 2 pixel wide line of mid grey (RGB 128, 128, 128). Thus on an area of high frequency (single pixel) detail or colour changes everything will become horrendously blurred! A checkerboard pattern of alternating black and white pixels will now just show as a solid block of grey! So Digital Color Meter is effectively downsampling the image to half it's horizontal resolution. I think that's correct?

Obviously it also becomes extremely difficult to get an accurate colour reading of a particular pixel since the pixels are all being blended together! Though any vertical component of an image is unaffected. Only pixels horizontally are being averaged.

Images look correct when viewed directly either on their own or on a website so it's only when viewing an image through Digital Color Meter I see it as blurred.

Anyway the upshot of all this is now I can't do my retro graphics work on any Retina Mac which is obviously extremely limiting as my MacBook Pro and any Retina Mac is now useless to me for my work!

Unless someone here can figure out what's going on and recommend a fix to Apple not only in the next macOS release, but going back to OS X Mountain Lion since that's when Retina was introduced so all Mac OS's from Mountain Lion to Ventura and beyond have the bug - until it's fixed! Maybe some Terminal code might be able to patch the bug until Apple properly fixes it?

Surely I'm not the only one who's come across the bug? I can't believe it wasn't noticed and fixed by Apple's bug testers back in 2012 or for the release of OS X Mavericks. It's not exactly an obscure bug that only shows under highly specific circumstances. If you use a Retina Mac and Digital Color Meter it's plainly obvious to see if you work with retro graphics or do 'pixel art'.

Please advise 'ASAP' before I submit a bug report to Apple or at least submit feedback to Apple as I'm not a developer.
