Probably not, all things considered.

I'd say worry about it later. Doing two scan lines is easy, and the overhead
probably won't make much difference, so you can always add it if it ever
becomes an issue. For intensive things like 3200 viewing you have to go direct,
which can be considerably messier, but you don't have to worry about that.
