Maybe we are on to something...is it possible the firmware really drops the 1024x600 mode due to this restriction?
Yes, the exact mode described by the edid is dropped due to containing odd horizontal timing values.

However the timing created by the CVT formula:

Code:

$ cvt 1024 600# 1024x600 59.85 Hz (CVT) hsync: 37.35 kHz; pclk: 49.00 MHzModeline "1024x600_60.00"   49.00  1024 1072 1168 1312  600 603 613 624 -hsync +vsync
has no odd horizontal timings, and so is supported by the Pi4 (and you have confirmed that the display is also happy with it).
