I can't explain the EGL_BAD_MATCH from that, the format+modifier is clearly
supported, and the other parameters for the function are definitely not wrong
either.

I think to find out more you'll have to ssh into the system, attach gdb to
kwin_wayland and step through EglDisplay::createImage to figure out where
exactly Mesa returns the error code.
