It did work!
Albeit there is some weirdness going on with brightness that causes the LEDs to flash random colors, and a bit of flickering. I thought it might have had something to do with WS2812B vs WS2812.
Here is my current config so far I am using to test:

I did toodle around with OpenBeken WS2812B control via PixelAnime driver last night. The lights were smoother, brightness worked correctly, and colors were more inline with default behavior.
I am gonna poke around their driver and see how it may overlap with belken_spi_led component.

This is great news, if it isn’t too much to ask - could you do a write up of what you did so a newb like myself could replicate it? I would love to get these things off of the tuya infrastructure.
I can do that next weekend!
But overall:
Use tuya-cloudcutter and push OpenBeken as custom firmware
For OpenBeken module configbacklog startDriver SM16703P; SM16703P_Init 36; startDriver PixelAnim
Perform OpenBeken home assistant mqtt discovery
I do plan on figuring out how to make the lights as smooth on esphome as it is for OBK.

Any update here? I am invested!

I have flashed these, with OpenBeken - but I have no been able to get the cfgpins to work. Do you have any insight?
I’m also running into some issues. @LearningESP - could you please share more in depth info on what you did, before it’s lost to time? Also, did you have any luck with ESPhome?
Maybe you have to set up lightpartitions? Like with this device: Using LSC 3203632.1 RGBIC+CCTIC Ledstrip with ESPHome - ESPHome - Home Assistant Community Also based on SM16703 chip.
@twoenter post reinvigorated me to play with this again… thank you!
