Hm, it's a bit of a wash really. The statue is missing a lot of high frequency details like tiny wrinkles, cuts, scales and etc mainly on the tail, legs and torso region, and that's a lot of missing details proportionally speaking. It really nailed the head, neck, feet and forelimbs but due to the inconsistency of other regions, it feels like a LOD 0 model without loading some high res textures lol.
BO Rex may not have as good of a head but the consistency in quality is far better thus a more complete statue to look at.
On another note, IS probably didn't add any additional zbrush detailing on the original model and I fear the original did have some really low res textures at the time, especially when you compare to the JW T Rex CGI, so the goal of 100% replicating the original CGI model kinda backfired.
You can clearly see how much details are missing.
