LCDM doesn't explain how the mitochondria function, or why my dog prefers to shit in the yard instead of in the house, so it is clearly a failed model for not having explanatory power on those observations
0) Galaxy curves
1) cmb observations
And a few minor ones.
The 0th was the motivation for dark matter.
The 1st is good, but also not predicted a priori by dark matter. In it's defense, it doesn't need fine tuning to work (it works out with ~the estimated amount of DM)
For all the minor ones there's a lot of fine tuning necessary to obtain the results. So it's not surprising that an LCDM model (which can select an arbitrary distribution of DM) can fit some sundry minor observations. Again, you're cherry picking the minor ones.
LCDM has a hard time with: external field effect, renzo's rule, Tully fisher relation (requires tons of fine tuning), early galaxies, why dense elliptical and lenticular galaxies as a rule have no DM, etc. those are all phenomena explained and predicted (except for Tully fisher) by e.g. MOND.
