Here's a better way to pass the time: Are there ways to justify the differences in appearance between the 1701 as she appears on DIS vs how she appears in TOS instead of taking it as a visual retcon?
Personally, up until Star Trek: Strange New Worlds was announced, I was hypothesizing that perhaps the Enterprise, post-"The Cage," was being used as a testbed for a new type of warp field geometry that required a different hull configuration, and that afterwards the ship had been restored to its prior hull configuration in time for TOS. Given the similarities between the DIS Enterprise and the TMP Enterprise, I imagined that maybe the data gained from its time as a testbed, after some refining that happened during TOS, informed the refit she and the rest of the Constitution class underwent in the 2270s.
SNW may nullify that hypothesis, though, depending on when it's set or what it establishes about the condition of the Enterprise under Pike's command.
