YES, reverse the connector.
I believe it serves as a reminder to adjust the color icc profile for the projector for color correction. (opinion on reason)
The obsolete RED part is a 630 nm deeper red but only 2000 lumen.
The new RED is 620 nm more amber red but is 3000 lumen. Blue and green meanwhile are 5000 lumens and the low efficacy of red is common.
This datasheet is short on engineering reasons but has the usually marketing BS about mercury-free bulbs ( yet fails to mention the gallium arsenide content.)
So my opinion is perhaps what I might have done to alert field service people to the issue but hide the obvious reasons.
There is no damage to the reverse connection, but it won't work. and if replaced with the wrong colour, it won't work well either. So do two wrongs make it right?
The normal rated current in the forward mode is 27 Amps.
