We notice the same, well sort of. Interesting comment though as one
would try to place bees where they had a mixed pollen source for spring
build up. I suspect that in most of these cases there is in fact mixed
pollen coming in (same colour) . As well we notice that some pollen is
more attractive than others, possibly because of oil content. And again
there is the possibility that if the amino acid profile is OK then
increased consumption may well overcome the total protein lack.
Also, how good a pollen appears to be depends on how soon after its flow
you ask the bees to work. And of course how good the one previous to
that was.

Well, you have to start somewhere.
