I think that it's pretty interesting that the only character who acknowledges Sasuke's Tsòkóyòmi break - is Itachi, and Sasuke ( :lol.. ) himself.. :lol.
Sasuke's abilities' are second to none - known at that point in time - sans Itachi.. The Databook 3 elucidates that the former was the strongest shinobi, at that point in time - sans Itachi.. The latter's abilities' made him be deserving of the illuminant accolade of the axiomatically "invincibility" title\hype, which only a certain, select few has acclimatized to - and has came close to - in the length, and breadth, of this serialization.
This indicates to me, that Sasuke did not break the magnificent illusory spell, tbh. But, I don't really think that this, is, a slight to the latter, tbh.. I mean, I don't really think that any character in this serialization - has the illusory skill, or prowess - to navigate through, and break such a powerful illusory magic spell..
"Time, Space, and even.. all mass.. is perfectly under my efficacy.. and, it is, a part of my domain in the pertinent, Dark Moon (or, Tsòkóyòmi.. .. ) Realm\Dimension.. .. " - Itachi's words to his opponent in that simulation - The Hatake Kakashi..
I think the fact that Itachi, bafflingly acknowledging the fact, that the Sasuke, broke his exaltingly, illuminantly, irradiating, glitterin' illusory magic spell, can be utilized as an "evidence" that has a "some" degree of credibility to a "certain" degree.. but.. then again :lol ( :lol.. .. ), Itachi was lying like stated explicitly - by the likes of Obito, so.. ( :lol .. ) so, there's that..
