The doubleDepthBuffer has this:

        this.ping = new THREE.WebGLRenderTarget(innerWidth, innerHeight, {
            type:          THREE.FloatType,
            depthBuffer:   false,
            stencilBuffer: false,
        });

        this.pong = new THREE.WebGLRenderTarget(innerWidth, innerHeight, {
            type:          THREE.FloatType,
            depthBuffer:   false,
            stencilBuffer: false,
        });

        this.frontFaceRT = new THREE.WebGLRenderTarget(innerWidth, innerHeight, {
            type:          THREE.FloatType,
        });

It may use the EXT_float_blend to do the rendering, which iOS doesn't support..
