RGB color accuracy compared to stock Tuya and ESPHome firmware #1082

Just want to say I love this project and I'm happy to help where I can, even if that's just opening a few bug reports to hopefully improve OpenBeken in comparison to ESPHome and Tasmota.

I'm using some SYLANIA Smart+ RGBW bulbs which are controlled by PWM. When comparing different firmware, OpenBeken seems to perform the worst compared to stock Tuya firmware and ESPHome.

I created a video to hopefully try and show the differences between the firmware running on the same bulbs:

Somewhat longer video, but the reds being fairly off between the 3:00 - 4:00 minute mark are noticeable in the video. Of course, I'd throw a Tasmota comparison in as well, but the lack of Tasmota support is the reason I'm here :laughing:

Thank you for pointing that out. We have some kind of RGB calibration tool created by contributor: https://github.com/openshwprojects/OpenBK7231T_App/blob/main/docs/led_gamma_control.md Do you think that it may help? Maybe we need to apply some kind of multiplier to colors by default to make red more red?

Did you find any solution to improve this? I've got a Nedis RGBW LED-strip that i just flashed and i'm seeing the same thing after flashing it.

I've simply flashed these bulbs to ESPHome.
