Apple TV post TvOS 11.2 HDR not working

I had setup my Apple TV 4K to work perfectly with my 4K HDR compatible TV and everything was working fine, however, after it updated to TVoS 11.2, I can no longer get it to work on 4K HDR. It works on SDR but says that TV is not supported for HDR, whis is this happening?

Does anyone have a solution or will I have to wait for a future software update.

I am using all high speed HDMI cables and my TV is the latest 4K HDR compatible Samsung TV, and I repeat it was working fine before the update.

Any help will be good
