Edit: Room is completely blacked out/light controlled.
you really can't improve CR with the screen. Maybe perceived contrast, i seem to be a LOT, like a LOT more sensitive to elevated black levels than i am to bright whites. so in my eyes, but certainly not a meter, a dimmer image with excellent black levels does look better. usually the only reason you'd want to reduce brightness is to avoid light bouncing off the screen, lighting up the walls, and then hitting the screen again. It sounds like in your room, there wouldn't be a good reason for a grey screen, or ALR since you wouldn't have much light bouncing around in there.
the contrast can actually be improved by a couple of things(not sure if possible in your room though). clamping down the iris is one, and moving the projector to the furthest throw distance is another. Both of these things help with the light control inside the projector, and the result is a higher native contrast ratio. this actually can be measured with a meter, and i believe is considered basically a rule for all projectors.
as mentioned before, an ND filter could also be a cheap and easy method to reducing black levels. Think of it like sunglasses for your projector. Probably not the best solution, but if your projector truly is 'too bright' and therefore has too bright of blacks, then $10 for an ND2 filter seems like a better bandaid fix than several hundred for a grey screen. both will just reduce the brightness of blacks and whites equally(not improving actual CR), but the usual advantage of the grey screen also reducing the affect of ambient light (the ND2 filter obviously does nothing for ambient light) doesn't sound like it's needed in your room. the filter can easily be removed when your bulb starts to dim, or you want the brightness back for HDR too.
it's not always the best method, but i tend to try the cheap, easy fixes first when the solution isn't well documented
-close iris (free and takes two seconds)
-move projector (might be free and easy, could be a significant remodel and not worth it at all)
-ND2 filter (cheap and super easy)
personally, i'd spend the money on calibration(pro or buying a meter so you can DIY) before a new screen.
