V8_UHD original firmware setting 4K color deviation issue

[zyjzy]

As the title suggests! When I set V8_UHD to 4K display, the TV shows noticeable color deviation. My firmware is the original version. I will first solve the problem from the software and flash it to Mars firmware to solve the 4K color deviation problem. It seems that there are many issues with the original firmware, and I'm not sure if this is an isolated phenomenon. Unfortunately, the Mars version does not support custom M3U or txt text IPTV channels.
