User-study percentages point in opposite directions in MAV3D and 4D-fy. The one independent-protocol re-run found (SV4D 2.0 on its own ObjaverseDy validation set) places L4GM close to Consistent4D, which is not the large lead L4GM reports on the Consistent4D benchmark. No source supplies a production-fitness test.

Curator GET 2026-10-23 of the sources not re-read (mechanical source evidence, not semantic verification): S1: HTTP 200, bytes equal to the producer pin; S3: HTTP 200, bytes equal to the producer pin; S8: HTTP 200, bytes equal to the producer pin; S13: HTTP 200, bytes equal to the producer pin; S11: HTTP 200, bytes equal to the producer pin; S5: HTTP 200, bytes equal to the producer pin; S6: HTTP 200, bytes differ from the producer pin; S15: HTTP 200, bytes equal to the producer pin; S16: HTTP 200, bytes equal to the producer pin.

Evidence claims:
- [sourced_fact] The papers use different metric families and protocols: CLIP R-Precision plus human votes (MAV3D), CLIP Score plus pairwise user study (4D-fy), LPIPS/CLIP/FVD on a seven-object synthetic benchmark (Consistent4D, DreamGaussian4D, L4GM, SV4D), CLIP-F/CLIP-O and image metrics on a 20-case held-out set (Diffusion4D), and view/frame FVD variants plus FV4D (SV4D family). Cross-paper tables carry copied or inconsistent rows: the DreamGaussian4D row in L4GM and SV4D tables (0.16/0.87) equals the Consistent4D row and differs from DreamGaussian4D own Table 3 (0.12/0.92); Consistent4D FVD is 1133.44 in two papers and 1133.93 in a third; L4GM calls the benchmark eight animations while Consistent4D and its uid file list seven. User-study percentages point in opposite directions in MAV3D and 4D-fy. The one independent-protocol re-run found (SV4D 2.0 on its own ObjaverseDy validation set) places L4GM close to Consistent4D, which is not the large lead L4GM reports on the Consistent4D benchmark.
