ICN2037BP and FM6124 - Are they the same?

Does anyone know if the ICN2037BP and the FM6124 LED driver chips are functionally the same? I have a panel that has the ICN2037BP chips that works with my Adafruit Matrix Portal S3. Adafruit sells a P2 64x64 panel that the product photo of the back shows ICN2037BP chips. I found these same Corman panels on Ali Express for $12.50 each (vs $50 each from Adafruit).

Coreman told me they used to sell Adafruit P2 64x64 panels with ICN2037BP chips but the last few batches have FM6124 chips that they say are identical. They also said they have P2 128x64 panels with 5 address lines and FM6124 chips. I have been searching for P2 128x64 panels that will work with the Matrix Portal S3 and think the Coreman panels may work but I need confirmation that FM6124 and ICN2037BP are interchangeable. Thanks!
