Imam Ibn Al-Jazari considers the Qira'ah of Ibn 'Amir Ash-Shami mutawatir, even when it differs with all the other nine Qurra'

Imam Ibn Al-Jazari (رحمه الله) considered *every individual one of the* ten Qira'at to be mutwatir, when the riwayat and turuq are in agreement...

even if one of the Qurra' differs with all other Qaris.

We can see an example of this in An-Nashr when Ibn Al-Jazari discusses the Qiraa'at of Surat Al-An'am ayah 137 and the linguistic nuances of it's multiple recitations.

He says, “Sufficient proof for this [i.e. issue of Arabic grammar] is this authentic, famous Qira'ah [of Ibn Amir] which has reached the level of *Tawatur*."

ويَكْفِي فِي ذَلِكَ دَلِيلًا هَذِهِ القِراءَةُ الصَحِيحَةُ المَشْهُورَةُ الَّتِي بَلَغَتِ التَّواتُرَ
