The top shot looks like Luke is at the beach on a sunny day. The bottom (v3) shot looks Luke is on a cold freezing stormy tundra.
Evidently the v3 hits the mark. The original SW filmmakers may have color corrected this particular scene toward a bluish tint to suggest coldness. This is an artistic application of lighting.
I couldn't agree with you more, well put.
