QR code is blurry

I'm experiencing an issue with viewing QR codes in PDF files on my Apple device. When I open a PDF file using Apple's default applications, the QR code appears blurry. However, when I open the same file with third-party applications, the QR code is clear. The file also appears clear on Windows operating systems. I'm looking for a solution to make the QR codes appear clear when using Apple's default applications. The screenshot shows the Data-Matrix code, but the same with the qr-code. I see this problem on all my Apple devices: iPhone 13, MacBook Pro 2016. And on several recent operating systems.

Do you have a display with lower resolution, such as 2K or lower?

on those displays, the doubling of TEXT sizes is not the default.

This problem is also visible on the iPhone 13 and iPad (6th generation) 2018. I don’t have other Apple screens.

Nothing happens, everything remains as it is. You can check for yourself.

If you open the file in Safari, you will see a blurred qr code. And if in Chrome, then it will be clear. In the screenshot, I used a special program that makes JPEG from PDF.
