UHP lamp has lower red output.
In normal mode projector is at D6500 in dynamic mode colortemp is higher.
Green and blue dominate but you get a brighter picture. Red is maxed out but green and blue have some headroom left.
With a red cc filter you can use the projector at it's maximum setting for red output. Green and blue are lowered by the red filter and the loss in green and blue can be compensated by adding some gain. Max lumens output will be a little less or equal depending on the headroom left in the red when the projector is at normal colortemp setting.
Contrast will be improved because the filter is reducing the light in dark/black scenes.
During 'total black' scenes stray light is reduced.
The light reduction in bright scenes is minimized by maximizing the gain settings while the light loss in dark scenes leads to deeper blacks. -> Better contrast.
