5DsR cracked rear screen

[Frodo]

I took my 5DsR hiking over the Christmas break. Most of the time it lived on by 24-105 in my Crumpler "4 million dollar home" over my shoulder and clipped to by backpack. Once I scrambled up a slope with my camera on the strap over my neck and it hit a rock and cracked the cover over the rear LCD screen (see photo). I doubt if an aftermarket screen protector would have prevented the damage, especially as it looks like the impact was from the side.

The display functions perfectly (and now that I am used to the crack, it doesn't bother me), but I have two questions:

- Is the protective cover user replaceable?
That for the 5D2 was replaceable as there was an air gap between the cover and the LCD screen. I think that changed in the 5D3. I understand that the 5DsR has the same rear screen as the 5D3 (please correct me if I'm wrong).

- Will the crack be more vulnerable to water ingress?
I guess that if the cover is bonded to the actual screen and if the bonding material is not cracked (I presume it is more flexible), there should not be a problem.
I could apply an aftermarket screen protector, but I dislike them as they reduce clarity and contrast of the screen.

Thanks

Unfortunately, the entire LCD screen must be replaced, they are a bonded assembly. You can get cheap Chinese replacements. The main reason to replace it is resale value, a $21 screen would subtract the several hundred dollars that Canon charges for replacement from the value of the camera.

Thanks Mt Spokane, you are a veritable font of knowledge.
Yes, this is as I feared. I have ordered a Larmor screen protector to reduce the risk of water ingress and grime building up in the crack.
I won't replace the screen at this stage, but what is the display quality of the cheap Chinese screens?

I've bought one for a point and shoot, It seemed fine, but I have no idea as to the quality for a 5DS. I doubt if it would be noticable unless someone was really trying to spot a difference. LCD screens are a commodity, Canon does not make theirs.
