Only if the surviving Ottoman Empire is one that diverges from OTL in the mid 19th Century at the latest, as during the reign of Abdul Hamid II persecution of minorities became more common (Hamidian massacres) which heightened during the Second Constitutional Era (Adana massacre, Armenian / Greek / Assyrian genocides) during this period along with the early republican period there was also conflict with Kurds that if the Ottomans continued could have been worse, again this all depends on what sort of Ottoman state is continuing. The continuance of a state that has committed these acts does not bode well for future peace, far from peaceful the late Ottoman period saw death and violence everywhere.
You could reason that a continuing Ottoman Empire will avert civil wars (Jordan, Lebanon, Syria, Iraq, Yemen), the Israel-Palestine issue, Islamic terrorism which would make the middle east more peaceful, however this assumes the Ottomans are not carved up by the western powers anyway, they put up stiff resistance during The Great War but without allies in a post war world there is little in the way of having a Skyes-Picot esque partition of the Levantine and Arabian lands of the Ottoman Empire. An earlier POD would also help to avert the persecutions of muslims during the Ottoman retraction if lands with significant muslim populations can be kept, the concern would be that pan-Islamism whilst helping to keep the late Ottoman state together could still lead to persecution and genocides of its Christian population anyway.
If the late Ottomans could maintain their territorial integrity than according to the violet line they would have access to Saudi oil wealth provided they could crush the house of Saud who had begun to rise during the late Ottoman period (The Great War put a pause on crushing them), then again this wealth might be exploited for the worse instead of the better so long as the authoritarian and suppressive strain of the late Ottomans continues.
The trouble I see is that to my knowledge Abdul Hamid II bought the empire more time as the situation was pretty dire when he took over and it was his authoritarian approach in that time of crisis which kept the empire together but this is what allowed his regime to begin the approach of violent repression of minorities. The first thought is to at least go back to the reign of Abdulaziz who was mostly useless.
Turkey reformed because its survival as a nation depended on it, as a depopulated nation with enemies and imperialist powers to all sides, if the Ottomans do not have the same concerns for their security and existance then they will not put in all the effort to reform that the early Turkish republic did, so we cannot see a surviving Ottomans as being of the standards of modern Turkey, even including oil wealth.
Additionally a Ottomans to survives for longer may still collapse in a similar fashion to OTL Yugoslavia.
