> simple to parse, memory-efficient, and easily implemented on constrained devices

have you considered (compressed) texture formats?

ASTC might very well meet your requirements, including performance on embedded hardware: https://en.wikipedia.org/wiki/Adaptive_scalable_texture_comp...

If not ATSC, also consider ETC and DXT.

ASTC, ETC, and DXT are indeed efficient formats, especially when hardware support is available. In my case, the target devices are microcontrollers without GPUs and with very limited RAM. A software decoder for these formats would require more resources than are realistically available. That is why I am exploring a simpler format that can be implemented with minimal overhead and predictable performance, even on very constrained hardware.
