The definition of semi-album is the opposite of what you have but a beautiful variant never the less!
 
Some one said it is not semi-album, but the lack of yellow and dark brown , remaining only the pink in this case can not be named flavum. In fact a small amount of yellow is present in column and staminode so how can we name this?
A commun one is down here for comparison

Seeing the green in the pouch in the last photo, now it looks more like a typical klotzscheanum to me albeit with a lighter pouch color. Here's a photo of one of ours for comparison.

How about variety albescens?

as in:al·bes·cent (l-b s nt) adj. Becoming white or moderately white; whitish. [Latin alb sc ns, alb scent-, present participle of alb scere, to become white, from albus ...
 
The white is beautiful....really beautiful! However, the photo with 2 flowers shows the one in the backgrownd with a green pouch. So, is the white from the fact that the flower has aged a lot? Does the green fade to white?

I agree with Rick H. This colour is more like var. albescens. Variety semi-alba specifically refers to white, colourless sepals and petals; but, with a coloured lip. This flower is the oposite of that. It's got no or little colour in the lip and more colour in the sepals and petals. The variety albescens is a much more accurate name.
 
It doesn't fit the semi-alba definition as we know it from Cattleyas, and there are certainly many approbiate names for this flower (forma albo-roseum would be my idea).
It is unique, rare, lovely and likely to be useful in breeding, and should be propagated, in my opinion.
 
Let us know if other flowers (from the same plant) also have that color. If not, it may have been caused by heat stress during the bud formation, and if that is the case, the next flower may be normal.
