I will connect a usb-serial adapter to the internal header to get the boot logs - these only have USB C for power but data lines not wired to anything.. I tried the 25% buffer and no noticeable change so far. That link to the docs is super helpful too, thanks!
Okay I tried changing the display dimensions to 160 and that fixed it, so must be related to buffer size like you said.. I'm wondering why as I've run this same code on an ESP32 C3 with similar ram.
dimensions:
width: 160
height: 160
But then I realized I am using the Arduino framework here and had used the esp-idf on the C3.. I had tried both before I got it working with the lambda but not since setting the SPI mode to 3.. And it works! I'm guessing just because esp-idf is more efficient with memory usage, still haven't hooked up serial converter to the debug header. Here is the working yaml https://github.com/clowrey/esphome-geekmagic-small-TV-pro/blob/main/small-tv-pro-lvgl-esp-idf-working.yaml
Thanks for your help again!
You might find the ESPHome debug:

Ahh!! that is super useful!! This is the output with esp-idf framework and working LCD

and here it is with arduino framework and no LCD - no logs showing LVGL working either unless I go to trace level debug - I am guessing the free heap being larger is because it failed to load the LVGL for some reason.. I will still get the hardware serial connected to investigate boot time errors more.

@clydebarrow Thanks for all your work on LVGL in esphome. Its coming along really well. Can you add the value_ofs_x and value_ofs_y properties to a button? I really like have the text offset a bit. I gives more room on the buttons for badges and other information. I can put in a formal features request if you want but this would be a request to update a feature that is not even released yet :)
@clydebarrow Thanks for all your work on LVGL in esphome. Its coming along really well. Can you add the value_ofs_x and value_ofs_y properties to a button?
No, that's not present in LVGL 8.4. I'll move to V9 when it's sufficiently stable.
And the docs are here: https://arc.net/l/quote/tggegklw
