I've been checking around for more info on that.
Since I couldn't find
any english scans of volume 11, I had to use the spanish release to go by (which considering the releases in latin america have been far more consistent consumers and the market there for Saint Seiya is overall a lot more rentable for the franchise, it should not be treated as inferior in fidelity).

"Como t├║ bien sabes, la temperatura extrema de congelación es el cero absoluto. ┬íSin embargo, incluso para m├¡ resulta imposible llegar a esa temperatura tan baja!"
"As you very well know, the extreme congelation temperature is the absolute zero. But, even for me reaching a temperature that low is impossible!"
Top left panel, Camus states he can't reach the absolute zero, even if he does get critically close to it.

"┬íTe mostraré cómo supero tu capacidad de congelación...! ┬íAunque no llegue al cero absoluto...!"
"I'll show you how I overcome your congelation capacity, even if I don't reach the absolute zero!"
Bottom left panel. Hyoga stating he's not planning to reach the absolute zero.

"Te lo promet├¡...! Te promet├¡ que aunque no llegara al cero absoluto... te mostrar├¡a cómo supero tus habilidades de congelación!"
Mid bottom left panel, Hyoga states the
exact same thing again. He's not reaching the absolute zero, but he'll surpass Camus.

"┬í┬┐Qué es esto?! ┬íEl rayo de congelación ha quedado suspendido en el aire, equidistante entre nosotros! ┬í┬íEso es absurdo!! ┬í┬íSignificar├¡a que Hyoga ha llegado al mismo nivel que yo!!"
"What is this!? The freezing beam is suspended in the air, equidistant between the both of us! It's absurd!! This would mean Hyoga has reached the same level as me!!"
Self explanatory, Hyoga is adapting and matched Camus' freezing power.

"┬í┬íLa armadura!! ┬í┬íLa armadura de oro se ha congelado!! ┬íE... entonces estaba en lo cierto...! ┬íPara destruir el ataud de hielo es necesario un poder de congelación superior al m├¡o! Una temperatura inferior a los 273 grados bajo cero, ┬í┬íO sea, el cero absoluto!!"
"The cloth! The Gold Cloth has been frozen! Then I was right, to destroy the freezing coffin, a congelation power superior to mine is needed - a temperature lower than 273 degrees below zero. In other words... the absolute zero!"
"┬íResulta que es ahora, cuando est├í a punto de consumir toda su vida cuando Hyoga supera a su maestro! ┬í┬íMediante la consecución del cero absoluto!!"
"It so happens it is now, when he's about to consume his entire life force, that Hyoga surpasses his master! Through the attainment of the Absolute Zero!"
It's clear by this point that Hyoga has consequentially reached the threshold of the absolute zero, as evidenced by Camus' gold cloth getting frozen.
There's some more statements that back up the fact that he's pulling a miracle from the seventh sense but they don't add nor detract from the feat, so I'll stop there.
I believe you were right, yeah. After having read the volume again, it's pretty safe to say Hyoga
ca reach the absolute zero through the power of miracles , much like Seiya was able to bust the central pillar. Camus however doesn't seem to be capable of getting close to attaining it from the statements or feats shown alone, Hyoga's Cyngus Cloth does not work as a comparable benchmark, since it's a bronze cloth, and it's freezing temperature is stated and shown to be -150┬║.
