In principle they should be equivalent but in practice, the straight
measuring path may be more sensitive to polarization. A 45 degrees
circular measuring field would "mix" the incoming light and de-polarize
it, but a low cost design would likely be more expensive to manufacture.
Given the strong directional dependent characteristic of LCD's, I'm
not sure you would really want a 45 degree measurement instrument for
this purpose. What it sees from 45 probably won't be the same color
or brightness as a normal user....
