Are Tohno and Ryougi's Mystic Eyes of Death Perception different?

Having read F/SN before I've decided to go through the whole Nasuverse in order, so having just finished Kara no Kyoukai and Notes. I've just started Tsukihime. Early in Tsukihime we see that Tohno Shiki sees the "cracks" in everything, including mundane objects and he cuts his bed with a fruit knife. In Kara no Kyoukai it's left a little unclear what exactly Ryougi Shiki can and can't cut but when she was trapped by Araya Souren in Paradox Spiral Touko mocks Souren for trapping Ryougi in the complicated infinite prison which she can escape with her eyes, saying that if he'd just trapped her in a regular concrete prison there'd be nothing she can do. As far as I remember in Kara no Kyoukai Ryougi never cuts anything non-living and mundane, it's always eirher a living thing or something magicak or conceptual. Without spoiling Tsukihime for me, are their eyes actually fundamentally different or is this a bit of a retcon or an inconsistency?
