How does this study affect the holographic principle?

In summary, a recent study has discovered a flaw in Emergent/Entropic Gravity, as it has been found that holographic screens do not behave according to thermodynamics. This may also invalidate the holographic principle, as it relies on the idea that information from a bulk is encoded on its boundary. The paper, titled "Surfaces away from horizons are not thermodynamic," explains that this issue undermines the key thermodynamic assumption of the Emergent Gravity program. While this program is not directly related to the holographic principle, it could have implications for other holographic principle models such as AdS/CFT or gauge/gravity duality.

In a recent study (https://phys.org/news/2018-08-flaw-emergent-gravity.html) it has been discovered an important flaw in Emergent/Entropic Gravity because it has been discovered that holographic screens cannot behave according to thermodynamics...

But then, doesn't this also invalidate holographic principle? Since in holographic principle, entropy (information) from a bulk would be encoded on its boundary, and according to this study holographic screens would not behave according to thermodynamics, wouldn't holographic principle models also be affected by these results?

Surfaces away from horizons are not thermodynamic
Zhi-Wei Wang & Samuel L. Braunstein

They only say "For surfaces away from horizons in the emergent gravity program the first law fails (except for spherically symmetric scenarios), thus undermining the key thermodynamic assumption of this program." In the text it appears that "emergent gravity program" refers to On the Origin of Gravity and the Laws of Newton. J. High Energy Phys. 2011, 29 (2011) which has nothing much to do with the holographic principle in general (eg, AdS/CFT or gauge/gravity duality).
