That seems to have fixed the issue! Thank you.Possibly. There was a recent bug fix to reduce the I2C clock used when reading the EDID on Pi5. See here.When I put the SDCard with this code in a Pi4, I always get a correct list of modes and EDID. Is the i2c interface different between Pi5 and Pi4?
If you use rpi-update you can get a kernel that has the fix. It is possible it will fix your issue.
