I solved double tap zooming and pinch zooming not staying by implementing the following minor code changes in TransformableImage/index.js and ViewTransformer/index.js:

"react-native-image-gallery": "2.1.5"

TransformableImage/index.js

let maxScale = 5;                            // change to whatever you want the max zoom in state to be
let contentAspectRatio;
let width, height; // imageDimensions

if (imageDimensions) {
    width = imageDimensions.width;
    height = imageDimensions.height;
}

if (width && height) {
    contentAspectRatio = width / height;
    // if (viewWidth && viewHeight) {         // code preventing zoom from staying based on image resolution
    //     maxScale = Math.max(width / viewWidth, height / viewHeight); 
    //     maxScale = Math.max(1, maxScale);
    // }
}

ViewTransformer/index.js

onResponderRelease (evt, gestureState) {
    let handled = this.props.onTransformGestureReleased && this.props.onTransformGestureReleased({
        scale: this.state.scale,
        translateX: this.state.translateX,
        translateY: this.state.translateY
    });
    // if (handled) {
    //     return;
    // }

    if (gestureState.doubleTapUp) {

My full patch file for the project is attached and includes a lot of minor changes like
